Problems solved by technology

[0003] The server may lose packets during the process of sending RTP packets to the set-top box. When the packet loss request is not timely, it cannot receive the response packet from the server, resulting in video playback freezes and unable to play videos smoothly.

Abstract

According to the set top box and the packet loss processing method provided by the invention, the set top box comprises the first network port, the buffer area and the processor, the RTP packet is read from the buffer area to the buffer queue, and then the packet loss request interval and the buffer rate are adjusted according to the transmission code rate of the RTP packet; and when the adjusted corresponding packet loss request interval is reached and packet loss exists, sending a packet loss retransmission request, and reading the RTP packet from the buffer area to the buffer queue at the adjusted different buffer rates. The transmission code rate of the RTP packet is acquired in real time, the packet loss request interval is dynamically adjusted according to the code rate, the packet loss request is sent in the early stage, the timeliness of the packet loss request is ensured, the cache rate is dynamically adjusted according to the code rate, the RTP data retransmitted by the server is timely read into the cache queue from the cache region, the timeliness of data acquisition is ensured, and the data transmission efficiency is improved. Therefore, the data integrity is ensured, the playing fluency is ensured, and the playing quality is improved.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a set-top box and a packet loss processing method. Background technique [0002] When playing a program, the set-top box sends a RTSP (Real Time Stresming Protocol) request to the server. After receiving the request, the server composites the audio data and video data into a TS (Transport Stresm, Transport Stream) data stream, and then adds Add the RTP (Real-time Transport Protocol, real-time transport protocol) protocol header, and finally send it to the set-top box in the form of RTP packets. [0003] When the server sends RTP packets to the set-top box, packet loss may occur. When the packet loss request is not timely, the server cannot receive the response packet, resulting in video playback freezes and smooth video playback. Contents of the invention [0004] The application provides a set-top box and a packet loss processing method, which can send...
